Bitbeam Presentation – CNC Build Club

Bitbeam

This week we have a presentation by Jason Huggins (@hugs) on Bitbeam and the Tapster robot he built with it.

jason-huggins-with-tapster

When:

Thursday, May 9th @ 7:00pm, upstairs in the electronics area

Topic:

Jason will give an overview of Tapster, his open source, 3D printable, mobile app testing robot. In addition to explaining why creating a mobile testing robot is not the worst idea you’ve ever heard of, Jason will give an overview of Bitbeam, the open source building toy that he developed, which Tapster’s made out of. He’ll cover his making journey as he’s experimented with laser cutters, CNC mills, and 3D printers to make Bitbeam. For fun, the talk will also include live demos of Tapster playing Angry Birds.

About Jason:

Jason Huggins is CTO and co-founder of Sauce Labs, a software test infrastructure company, and is the original creator of Selenium, a popular open source web testing tool. In 2011, for an art project he was working on, Jason created Bitbeam – a 3D printable LEGO-Technic-compatible construction toy. Jason lives in Oak Park, Illinois.

Last Night’s CNC Build Club

DSC00514

We had a great meeting last night.  We had over a dozen people working together to wire up a CNC control box.  At one point we had three soldering irons going at the same time.  Here is the pile of parts we started with.

Starting Pile Of CNC Parts

 

Here are some people wiring the box.  A really nice job was done using wire ferruls wherever we could.  How many hands can fit in that little box?

Here is the nearly completed box.

Thanks to Chris, Matt, Aeva, Patrick, Donald, Steve, Jason & Alex, Cat, John, Will, Gabe, Norm, Allen and Colin.  Next week we will be testing the motors, adding limit switches and configuring the software.

We will start with Mach3, then switch to EMC2 when we find a dedicated PC for that.  Chris and John I think mentioned they do time at Free Geek.  I am sure they could find a little PC.

Special thanks to Automation Technologies Inc for giving/lending all the parts.

CNC Build Club

Automation Technologies 3D Gantry

The CNC Build Club meets just about every Thursday at 7:00pm.  This is a weekly meeting of Chicago area people passionate about designing, building and learning how to use digital fabrication equipment.  Non members are welcome .  Each meeting starts with a round robin introduction followed by a little discussion and often a presentation or training session.  We also often have a group project going on.

This week we are going to start putting together a small CNC milling machine.  The machine was lent to us by Automation Technologies Inc.  Right now the machine is just the mechanical platform.  We need to add the motor controls, limits switches and setup some software.  The goal is to create an easy to use work center that we will do some projects on.  The plan is to sell the machine at a discount to someone in the group when we are finished. If you don’t know anything about CNC, don’t worry, you can still help.  The goal is to teach, learn and use.

Pictures from the Scanning Electron Microscope

A few nights back, Brian and I took some images from the SEM. We exported them into TIF format, and then copied them via Sneakernet, a.k.a. using 3.5″ floppy disks and a portable USB floppy reader. I converted them into .png files. Click them for full 1024×768 resolution, the limit of the Leica image capture board. I’m very happy with how they turned out.

NERP tonight! Eric Stein: RPi hardware i/o and ZeroMQ

ERP is not exclusively raspberry pi, the small computer and embedded control interest group at Pumping Station:One in Chicago.

Tonight, Eric Stein, who is Chief Cat Herder and president of Pumping Station:One will take time out of his busy schedule to show us a Raspberry Pi and Python based system that sends messages by passing messages.

eric-beer-240
Eric’s system, which is currently in development, receives input from IRC (internet relay chat) and responds by playing an informational message over one of several louudspeakers located around the PS:1 facility. The Pi does text-to-speech conversion on stored messages and i/o logic and control to select the appropriate audio output channel.

A very interesting aspect of the system is the use of ZeroMQ to pass control messages between the Pi and and a server that does something important that Eric will explain. From wikipedia:

“ØMQ (also spelled ZeroMQ, 0MQ or ZMQ) is a high-performance asynchronous messaging library aimed at use in scalable distributed or concurrent applications. It provides a message queue, but unlike message-oriented middleware, a ØMQ system can run without a dedicated message broker. The library is designed to have a familiar socket-style API.”

Beer Church: Beer Tasting, Sunday April 7th, 2PM

Hello everyone!

Since the last Beer Church, Eric & co’s This Is Your Grain On Chocolate has come and (sadly) gone. We’ve got 5 different Beer Church creations hidden away in bottles, and they’re all coming out to play this Sunday. Bring them some playdates in the form of a bottle of your favorite off-the-beaten-path beer – whether your own homebrew, or from a store. We’re not picky (but we are snobs)! Small beer steins will be provided to consume from, but you’re welcome to bring your own chalice.

Once we’re done with the tasting, Eric will demonstrate how to use a Soxhlet Extractor to create flavor extracts from a fruit or herb (undecided yet) – so far, we’ve used 2 of them – in our dearly departed friend, This Is Your Grain On Chocolate.

After we taste & make some flavor, we move forward to build out fun time. Our current fermenter was built hastily to get us off the ground and we’re going to try to get started replacing it with a better designed and larger home for brews. Chillmon has a new circuit board courtesy of Ryan, and we might find the time to get it working with the new fermenter. Along the way, we’ll figure out a superior storage solution for our gear (this time, with organization!). No brew today, but we’re hoping for a productive and fun day of woodworking, tasting beers, electronics, programming, and tasty science.

tl;dr

When: Sun April 7, 2:00PM-5:00PM
Where: Pumping Station: One, 3519 N Elston, Chicago
Why: Because you like tasting beer & building things
What: Potluck & Beer Church’s brews beer tasting, Buildout
Extra Credit What: Demonstration of Soxhlet Extractor flavorant creation for use in beer making
Who: Anyone 21 years or older

Scanning Electron Microscope Update

SEM and RyanBack in January, we got word that Philip Strong, a past member of PS:One, worked for a company that needed to get rid of a working scanning electron microscope and was considering donating it to PS:One. While we have an existing SEM in the space (a Leica S440, owned by JP, a member), this one supposedly was fully functional, had documentation, and we could get some help from the microscopist, Susan Young, who used it. Of course we were interested!

On Monday the 18th, I learn that yes, the donation was approved, but with a catch: It had to be moved on Saturday the 23rd! Read the rest of this entry →

Boardforge gantry Ver 0.3a in development (Ed_B)

Several members of Pumping Station:One are collaborating on a project to produce a pick and place machine. PnP machines are robotic assembly devices that place electronic components on circuit boards as part of the soldering process. The software that will run the machine is made of several distinct subsystems including motion control and computer vision. Jay Hopkins has been doing some experiments to determine whether a Raspberry Pi can serve as the on-board controller for the machine. Tonight he’ll show nerp some of his progress. Teaser: OpenCV _will_ compile on the Raspberry PI!

Beer Church Beer Tasting & Brewing a Rhubarb Wheat Ale: January 20th, 1PM

Hello again from Beer Church, the brewing group at Pumping Station: One! This past Sunday the 6th, we tasted & kegged a beer (the Doppelbock’s leftover batch, titled Kinderbock Son von Doppelbock), tasted our previous foray into Mead-making (I Didn’t Mead It That Way, and brewed an American IPA with Cardamom titled Putting the India back in IPA, all grain. It was an all-around great day and the ferment bucket for the IPA is bubbling along crisply in the fermentation chamber. Today at N00B’s Paradise (Pumping Station: One’s event for newcomers), we tapped the Doppelbock – it’s good.

We just cleaned the taps. The bar is operational. We’re rocking and rolling.

So, on the 20th we’ll do it all again. This time we’re going to create a Rhubarb Wheat Ale; this is something few have done. The idea comes from Brittany, who is so enthused with the idea that we’ll oblige and make it happen. If this kind of idea appeals to you – and why wouldn’t it – then you should come visit Pumping Station: One on the 20th at 1PM. You don’t have to be a brewer; you can watch, or participate. Before the brew we’ll go over the basics of how brewing works while tasting our previous brews, including:

* Doppelbock
* I Didn’t Mead It That Way
* Pumpkin Ale
* Whatever bottle you bring! Find something in your fridge or the store that you think most people haven’t had, and introduce us to it.

Another new addition to equipment is our BeerGun which we can now use to bottle beers. This and future brews will have a small amount taken aside for a limited run bottling. Part of that bottling run will be granted to those who took part in brewing of the beer; 2 bottles for the brewmaster and 1 for all the helpers who stuck around until the end. Of course, this doesn’t happen immediately; the brew has to make it through brew day, fermentation, maybe racking for secondary, kegging, kegging, and bottling first. This in mind, if you help out on brew day you’ll get something to show for your efforts that’s a little more solid than being able to come in and try your brew on tap. The rest of the bottles will be saved for future Beer Church events so we get to savor them for a little bit longer. Our brews tend to go by pretty fast after they go on tap, since they’re so good (so far).

Nitty Gritty

When: Sunday January 20th, 1PM. We expect to brew brewing until around 7 PM or so, but you don’t have to hang around the whole time if you don’t want to.
Where: Pumping Station: One, 3519 N Elston, Chicago
What: Beer tasting and brewing hands-on
Who: Anyone 21 or over, Pumping Station: One members or not!
Why: Because beer is a worthy purpose for your Sunday afternoon
To Brew: “Rhubarb Waves of Grain” – Orange Ginger Rhubarb Wheat Ale
Brewmaster: Eric Stein

See you on Sunday. Follow along at our twitter, @ps1beerchurch.
